MARSHALL L. BASSETT, OF WEST HAVEN, ASSIGNOE TO HYRON H. KIN SLEY,

OF WALLINGFORD, CONNECTICUT.

IMPROVEMENT IN ATTACHMENTS T0 METAL-BLANK-FORMING MACHINES.

Specification forming part of Letters Patent No. 207,840, datedSeptember 10, 1878; application filed January 31, 1878.

To all whom it may concern:

Be it known that I, lVIARSHALL L. BASSETT,

of West Haven, in the countyof New Haven and State of Connecticut, haveinvented certain new and useful Improvements in Attachments to Machinesfor Forming Metal Blanks; and I do hereby declare that the following isa full, clear, and exact description thereof, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

The object of my invention is to provide an attachment for die-operatingpresses, rolls, and other analogous devices or machines, whereby theblanks'of malleable metal will be regularly laid in order as receivedfrom the dies, for convenience in packing.

The nature of said invention consists in a metallic guideway,constructed and braced substantially as hereinafter set forth andclaimed, the same being an improvement on the device secured to J. H.Baird by Letters Patent No. 90,914, June 8, 1869.

In the accompanying drawings, Figure 1 is a perspective view of myattachment in its simplest form, adapted to be applied to dieoperatingpresses or punches. Fig. 2 is aperspective View of the same with aninclined trough added, to adapt it to be used with rolls.

A designates one of the supports of my attachment, and A the other, along fiat inclined platform or guide-plate, B, being secured in anyconvenient manner firmly upon the same. The end B of said guide-platenearest to support A is curved almost Vertically upward, and is bracedby a similarly-curved plate, a, formed on the upper end of support.

A. The latter is made somewhat lower than support A, so that there is anincline in said plate B, and is arranged at a little distance therefrom.

D designates a curved plate, which corre= sponds to the shape of B, andis arranged a little in front of the same. Its lower end extends a shortdistance beyond the curve in. the main guide-plate B, and is parallel tothe in: clined flat part thereof. Said plate D is sup ported by curvedplates E. which are rigidly attached to curved part B" of mainguideplate B.

Said parts B, C, 0 D, and E E together partly inclose a passage-way,which receives at the top the blanks as they come from the dies, anddelivers them regularly in order on edge at 'the lower end, ready to bepacked away. In so doing the handle of the blank is guided partly bycurved plates E E and partly by the parts B and D above described, andthe edge or end of the blade or bowl is guided by the curved part C ofend guide, C. The incline of guide-plate B tends to prevent the blanksfrom falling from their edges to their faces as delivered, which wouldinsure the disorder of all succeeding ones.

F designates wooden blocks, which fill the passage above described atthe outset of the operation, but which are gradually forced downward asthe blanks are fed in above them. They are removed as discharged fromthe lower end of the passage. Their ofiice is to support the blanksuntil there is a sufficient number of these latter to supportthemselves.

G, Fig. 2, designates an inclined trough, recessed at g to correspond tothe form of the blanks, and adapted to transmit the latter from therolls to the upper end of the guideway above described. It is supportedby means of plate G from curved part B of the main guide-plate B, anddelivers the blanks between the upper end of said curved part B and thecurved plate E. This trough is not used when the attachment is appliedto a punch or press for operating dies.

The press or punch forces the blanks one after another into and alongthe gnideway, no other feeding device being needed.

The space between inclined plate or plat form B and end guide-plate, C,and also the partly-open construction of the curved end of theattachment and the entire openness of plate B, except at the curved partB, enable the operator to readily reach the blanks from behind, from oneside, and from below at any stage of their progress, and to set rightany accidental displacement or change of position.

This attachment may be used in connection with the manufacture of manydifferent kinds of metal blanks, and I therefore do not confine it toany particular application. Its form and construction may beconsiderably varied without departing from my invention.

Having thus described said invention, what I claim as new, and desire tosecure by Letters Patent, is-

An attachment to blank-forming machines, provided with a guiding-platearranged at some distance from the edge of the deliveryplate orplatform, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

MARSHALL L. BASSETT.
